The invention belongs to the technical field of waste water treatment and reuse in exploitation of oil and gas fields, and concretely relates to a fracturing flow-back fluid recycling treatment process. The fracturing flow-back fluid recycling treatment process is characterized by comprising a fracturing well head, a high-pressure gas-liquid separation device, a filtering cylinder filter, a gas combustion pot, a sterilization processing apparatus, a pH value adjusting and metal ion deposition apparatus, a flocculating settling apparatus, a low-pressure three-phase separator, a fine filter, a liquid storage tank, and a sand collection pot, the technical problem that fracturing flow-back fluid cannot be subjected to on-line recovery and re-utilization can be solved, and the problems that pollution environment and cost are high, the time consuming of the treatment process in the prior art for the fracturing flow-back fluid is long, and land occupation of processing equipment and the liquid storage tank is large can be solved. The treatment process realizes fine recycling of the fracturing flow-back fluid and on-line processing and recycling of the fracturing flow-back fluid, reliabledegree of the treatment process is high, operation is simple, on-site enforcement performance is strong, the processed flow-back fluid is used for fluid preparation construction, application propertyis stable, liquid sand-carrying capacity is strong, utilization rate of the flow-back fluid can achieve 98%, and on-site construction cycle is shortened.
